Lubricating oil capable of reducing the environmental burden and effectively obtaining the additive effect in a lubricating oil composition having a low content of metal element, phosphorus element, sulfur element, and nitrogen element Providing a composition. SOLUTION: Based on the total amount of the lubricating oil composition, the lubricating base oil is contained in an amount of 98% by mass or more, the metal element content is 0.1% by mass or less, the phosphorus element content and the sulfur element content. And a lubricating oil composition in which the content of nitrogen element is 0.1% by mass or less, the lubricating base oil is a synthetic hydrocarbon oil, and the lubricating oil composition The lubricating oil composition further comprising at least one selected from sarcosine acid derivatives and acidic phosphate ester amine salts, an amine-based antioxidant, and a benzotriazole-based compound.
